Hi Randy,

It is development stage 1, which means we are all pretty busy, so
that's why no one had looked at your bug yet.

I cannot get the "smaller reproducer" to fail (with trunk); but your
minimal testcase in comment 1 fails alright (needs no compiler options
at all):

81317-2.c:4:21: internal compiler error: Segmentation fault
                     ( 1, jsimd_ycc_extbgrx_convert_altivec_outptr )
                     ^
0x102e1ad4 tree_class_check(tree_node*, tree_code_class, char const*, int, char 
const*)
        /home/segher/src/gcc/gcc/tree.h:3205
0x102e1ad4 altivec_resolve_overloaded_builtin(unsigned int, tree_node*, void*)
        /home/segher/src/gcc/gcc/config/rs6000/rs6000-c.c:6458

(The first arg to tree_class_check is NULL).

So, confirmed.
